The Bose PowerSpace P4300+ is a high-performance 4-channel Class-D amplifier with integrated DSP, engineered for commercial audio installations requiring flexibility, control, and efficient deployment. Delivering 4 x 300W of output power, it combines amplification and advanced signal processing into a single compact 1U rack unit, making it an ideal solution for multi-zone audio systems.
Designed as part of the Bose PowerSpace+ ecosystem, the P4300+ enables installers to streamline system architecture while maintaining precise audio control across multiple zones and applications.
The PowerSpace P4300+ delivers 300W per channel across four independent outputs, providing a total of 1200W system power. This makes it suitable for medium to large commercial installations requiring consistent coverage and reliable performance.
Typical applications include:
Its four-channel design allows multiple speaker circuits or zones to be powered from a single amplifier, reducing rack space and simplifying installation.
The P4300+ features load-independent outputs, allowing full power delivery to both low impedance (4–8Ω) and high impedance (70V/100V) speaker systems without requiring bridging.
This enables:
This dual compatibility is essential for commercial environments with varied system requirements.
A key advantage of the PowerSpace P4300+ is its onboard DSP engine, which provides comprehensive audio processing without the need for external equipment.
DSP functionality includes:
These features ensure optimised system performance and consistent audio quality across all connected zones.
The amplifier includes full mixing capability, allowing multiple input sources to be assigned and distributed across different listening areas.
This makes it particularly effective for:
The P4300+ features an integrated web-based configuration utility, allowing installers to set up and manage the system via a browser interface.
This enables:
This significantly reduces installation time while improving accuracy.
Designed for commercial environments, the amplifier includes advanced paging and integration capabilities:
These features ensure seamless integration into commercial AV and safety systems.
The P4300+ includes Bose I-Share functionality, allowing channel pairs to be combined to deliver up to 600W into a single output zone when required.
This provides:
Utilising Class-D amplification, the P4300+ delivers high output with improved energy efficiency and reduced heat generation.
Key benefits include:
An auto-standby mode further reduces energy consumption when no signal is present.
The P4300+ is designed for seamless integration into commercial AV systems, featuring:
This ensures compatibility with mixers, DSP systems, and external control interfaces.
Housed in a standard 1U 19-inch rack chassis, the P4300+ offers high power density in a compact footprint. Its robust design and front-panel status indicators allow for straightforward installation and system monitoring.
The Bose PowerSpace P4300+ is widely deployed across commercial audio environments:
Its combination of DSP, multi-channel amplification, and flexible control makes it particularly suited to multi-zone systems.
